[eruby] Add GetCommand to erb linter

Browse Source

GetCommand conditionally adds a filter (implemented as inline Ruby code
in the command line) to transform some of the problematic
Rails-specific eRuby syntax. Specifically, <%= tags are replaced with
<%.

This does not reduce the effectiveness of the linter, because the
transformed code is still evaluated.

This solution was suggested by @rgo at
https://github.com/w0rp/ale/issues/580#issuecomment-337676607.
